EV Charging Reservation Timing for Balancing Power Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing reservation management systems for charging stations do not efficiently accommodate the longer duration required for balancing power control, making it difficult for electrified vehicles to make reservations that align with power supply and demand balancing requests.
Innovation Solution
A server-based reservation management system that sets a longer reservation time period for charging stations when a balancing power control request is made, ensuring that the electrified vehicle can perform the necessary power control operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the reservation time period is set to a standard duration for normal charging control, then the efficiency of charging station utilization is improved, but the electrified vehicle cannot perform balancing power control which requires a longer time period
Solution Approach 1:
The reservation management system dynamically adjusts the reservation time period based on the type of power control requested. When balancing power control is requested, the system extends the reservation time period beyond the standard charging duration, allowing the electrified vehicle to remain connected and perform power supply to the grid. This dynamic adjustment resolves the contradiction by making the reservation system flexible rather than fixed, accommodating both efficient normal charging and extended balancing operations.
Solution Approach 2:
The system changes the time parameter of the reservation based on the control mode. For normal charging control, a standard reservation time is applied, while for balancing power control, an extended reservation time period is set. This parameter change allows the same charging station to serve different operational requirements appropriately, enabling both high utilization efficiency and adaptability to balancing requests.
2Adaptability or versatility
If the reservation time period is extended to accommodate balancing power control, then the electrified vehicle can respond to power supply and demand balancing requests, but the efficiency of charging station utilization may be reduced due to longer occupation time
Solution Approach 1:
The system segments the reservation management into different time periods based on control type. Normal charging reservations and balancing power control reservations are handled with different time period settings. This segmentation allows the charging station to be efficiently utilized for standard charging while providing extended access specifically for balancing operations, preventing the longer occupation time from negatively impacting overall utilization efficiency.
Data Source
AI summary
A server includes a communicator and a processor. The communicator is configured to receive a reservation request signal requesting a reservation to use a charging station by an electrified vehicle. The reservation request signal includes information indicating that balancing power control is requested, when the electrified vehicle wants to perform the balancing power control. The processor is configured to set, based on the reservation request signal, a reservation time period during which the electrified vehicle uses the charging station. The processor is configured to set the reservation time period to a longer period when the reservation request signal includes the information indicating that the balancing power control is requested than when the reservation request signal does not include the information indicating that the balancing power control is requested.
